I wish to re-order graded items in the gradebook. It seems simple enough, so I tried simply clicking on the 4-way arrow next to the item and dragging it to the desired location. Unfortunately that doesn't work - when I attempt to drag it, a circle with a red line appears, and the item snaps back to it's original location.
What I've tried: Chrome, Firefox and Edge; hiding/unhiding the item.
